Right now, yes, the main problem is having ACF4 and 5 both active and they are not compatible with each other. That should be resolved, hopefully soon. I don’t know Elliot’s timetable for getting ACF5 released to the WP repo, but I’m hoping that it’s very soon.

You’re theme can check the version of ACF that is active and display an admin notice

add_action('init', 'my_theme_check_acf_version');
function my_theme_check_acf_version() {
  $acf_version = acf_get_setting('version');
  if (version_compare($acf_version, '5.0.0', '<')) {
    // the version above could be changed to whatever
    // version your theme requires
    add_action('admin_notices', 'my_admin_notices_function');
  }
}
